Análise inelástica avançada de pórticos planos de aço considerando as influências do cisalhamento e de ligações semirrígidas
(Universidade Federal de Minas GeraisUFMG, 2010-10-15)
Conventional analysis of steel frames is usually carried out under the assumption that the beam-to-columns connections are either fully rigid or ideally pinned. However, most connections are of type semi-rigid and their ...
Análise inelástica de pórticos planos considerando a plasticidade distribuída e o efeito das tensões residuais nos perfis estruturais de aço
(Universidade Federal de Minas GeraisUFMG, 2006-10-27)
A geometrically exact finite element formulation to consider material and geometric nonlinearities of steel plane frames is presented. The distributed-plasticity analysis for members with rigid-pinned joints and residual ...
Um estudo da estabilidade de pórticos considerando o fator do comprimento efetivo e as forças nocionais
(Universidade Federal de Minas GeraisUFMG, 2010-12-10)
The objective of this work is to study the steel frames stability considering the application of the effective length factor and notional loads in the analysis of these structures. To achieve this goal, the characteristics ...
Estudo da influência do encruamento do aço e das tensões residuais no comportamento inelástico de pórticos planos via análise avançada
(Universidade Federal de Minas GeraisUFMG, 2010-05-21)
In this work a geometrically exact formulation to consider material and geometric nonlinearities of steel plane frames, by Finite Element Method (FEM), using the concepts of distributed-plasticity is presented. An overview ...
